ake Erie and Lake Superior — two of the five
that make up the Great Lakes — broke records for water levels this May.
Lakes Michigan and Huron could follow suit.
Naturally, climate change is getting the blame. “We are undoubtedly
observing the effects of a warming climate in the Great Lakes,” says
Richard Rood, a University of Michigan climate scientist.
But just a few years ago, climate scientists were insisting that a warming climate would cause water levels to decline. .........
The truth, of course, is that water levels in the Great Lakes vary
over time. And, as a matter of fact, they varied far more in the past
than they do now. A U.S. Geological Survey notes that “prehistoric levels exceed modern-day fluctuations.”
It says that “Prehistoric variations in lake levels have exceeded by
as much as a factor of 2 (that is, more than 3 meters) the 1.6-meter
fluctuation that spanned the 1964 low level and the 1985-87 high
level.”
And, as anyone who’s ever lived near the Great Lakes knows, the lakes themselves were formed
in the wake a massive change in the earth’s climate — when the glaciers
receded at the end of the Ice Age roughly 14,000 years ago.
So if the lakes’ huge fluctuations in the past weren’t caused by
mankind’s burning fossil fuels, why are scientists so convinced that the
far more minor changes happening today are?
The reason is simple. Climate scientists can blame anything they want
on global warming. The climate models are imprecise enough that no
matter what is happening they can point to it as proof that man-made
climate change is happening. Too much rain, too little rain, bitterly
cold winters, mild winters, more snow, less snow, rising water levels,
falling water levels — they can attribute “climate change” as a cause of
it all.
But if nothing can disprove a theory, and every event, no matter how
contradictory, is proof that the theory is valid, is that really
science? Sounds more like a religion to us."
